Almstins

Learn

Use crypto without the guesswork.

Almstins is five read-only tools for the moment before money moves: the second before you send, sign, or advance funds. This page lays out each one, what it does, what it costs, and where to learn it. Every item links to its page.

Read-only. No wallet connection, no keys, no custody. Almstins verifies, warns and flags; the decision is always yours.

The five tools

Two for anyone who holds or sends crypto. Three for businesses, lenders and the people who run AI agents. Pick a tile to read how it works.

Anyone about to send

Wallet & Site Checker

Free, no login

Paste or scan any wallet address or website and check it against independent risk sources before you send a thing. Each source’s answer is shown, and a result that could not see enough says so instead of reading clean.

  • Scam, phishing, honeypot and sanctions checks
  • Full scam checks on Ethereum, BNB Chain and Polygon; sanctions checks on Bitcoin, Litecoin, Solana, Tron and Sui
  • Sources include GoPlus, Chainalysis sanctions screening, honeypot.is and the OFAC list
  • Website checks against MetaMask, ScamSniffer, OpenPhish, Google Safe Browsing, VirusTotal and URLScan.io
  • Red, yellow or green, with each source’s answer shown
  • Scan a QR code with your phone camera; it is read on your device
  • Wallet age and activity shown as plain facts, never as a verdict
  • Shows when an address is a proven Verify destination

Lookups only: a check sends the address or link and nothing about you, and never submits anything for scanning. A clean result means no listed source has flagged it yet.

Anyone with more than one wallet or exchange

Wallet Watcher

Free up to 3 wallets

Everything you own across wallets, exchanges and DeFi in one place, with cost basis, realized gains and a full tax breakdown. Read by public address; nothing to connect.

  • Wallets on Ethereum, Polygon, Avalanche, Bitcoin, Litecoin, Solana, Sui and Rootstock
  • Aave and Sovryn DeFi positions
  • Exchange imports: Coinbase, Kraken, Gemini, Crypto.com, Robinhood, Exodus, Cash App and Venmo
  • Cost basis and realized gains (FIFO), short and long term
  • A research desk for your own transactions that are missing a purchase record or cost basis
  • AI Triage to sort unresolved transactions (paid plans)
  • Price and Aave health-factor email alerts
  • Signed, tamper-evident Year Summary PDF anyone can verify (Unlimited plan)

Almstins organizes records; it does not file taxes or give tax advice. The accountants who help you can read the same records.

Businesses, platforms and exchanges

Verify

Free during early access

A business registers the receiving addresses and payment links it publishes and proves they are really its own, so a customer can check a QR code or address before paying and spot one that was swapped or faked.

  • Prove control with a tiny payment from the address to itself, a file or DNS record on your domain, or an encrypted address list
  • Two public levels: Claimed, and Verified when backed by your own domain
  • “Scan before you pay” page: customers check any sign or QR, no account needed
  • Printable QR code for tables, registers and invoices that customers scan to check the address
  • Ongoing checks of what you publish, with email alerts to you
  • Only proven destinations are ever shown publicly
  • Exchanges: let users confirm official deposit addresses before they send
  • Developers and AI agents: a pre-send destination check API

Free early access: up to 3 destinations (2 wallet addresses and 1 payment link or QR). Verify proves control and publication, not that a business is honest.

Lenders and the businesses they finance

Receivables and milestone desks

Free, one contract at a time

A shared, signed record for invoice financing. A business records a receivable, lenders record the financing they extend against it, and anyone holding the receivable’s ID can see what is already financed before advancing more. The milestone desk does the same for staged work: a sealed schedule, inspectors who attest each stage from a single-use link, the funder’s payment record, and a dated close.

  • Record a receivable once; each lender’s financing is added to the same record
  • See how much of an invoice is already financed
  • “Seen before?” check: ask whether an invoice is already on record before advancing
  • Debtor confirmation through a single-use link, no account needed
  • Every entry signed and time-stamped on Bitcoin
  • Records age in the open: current, in grace, past due, or lapsed after six months
  • Email reminders to lender and business as a record goes stale
  • Automatic warnings for look-alike invoices
  • Milestones: a sealed schedule, inspector attestations with photos and a signed form, the funder’s payment record, and a signed close
  • Works for any invoice, crypto or not

A voluntary record that helps lenders spot double financing. It shows what the parties themselves recorded, and it never moves money. Free holds one open contract at a time, a registered claim or a sealed project; Standard holds ten.

People who run AI agents that pay

Agent Vault

Free, 3 agents

Register each agent, the wallets it pays from and the addresses it may pay. The agent asks before it sends, and the Vault keeps a dated record of every answer and every transfer, with a daily report you can download as a signed PDF.

  • Pre-send check API: one request, no login; the answer is proven, mismatch, unanchored or unknown
  • An outage is never a pass; the rule for the agent is proceed only on proven
  • Every address screened as you add it and at every keyed check: sanctions lists, scam screening, domain proofs
  • Every direct transfer of an agent’s wallet on Ethereum, Polygon and Avalanche, in and out, with whether the other side was on your list
  • A payment to an address not on the list, with no check before it, is marked unmatched and emailed to you at once
  • Emails never show an address, a label or an amount
  • A daily report as a signed PDF, and a History page of where your agents’ money came from
  • Free plan: 3 agents, 15 addresses, 5 wallets per agent, 5,000 recorded checks per agent per day

Agentics verifies, warns and flags; you decide. It never holds keys and is never in the payment path. Paid plans come later; nothing to buy today.

What we believe

Trust you can check, not trust you have to take. Six principles shape every tool.

1 Read-only. No custody, ever. Almstins reads public data and the files you choose to import. It never asks you to connect a wallet, never holds keys, and never moves funds, so there are no keys on our servers to steal.
2 The evidence, then your decision. Every result shows which sources said what. Almstins warns and flags. It never makes the call for you, and nothing in it stands between you and your money.
3 Proof, not promises. Year Summary exports, Agent Vault reports and receivables records are signed, so anyone can check them against our published key, and receivables records are also time-stamped on Bitcoin. We call it verifiable trust.
4 Private by design. We never ask for your name to sign up. A check sends only the address or link being checked, never who you are. No ads, no selling data, and Almstins does not file scam or fraud reports about anyone.
5 Honest about limits. No star ratings or reputation scores: popularity is not trust, and scammers can buy volume. When a check cannot see enough, it says so instead of showing a clean result.
6 Safety stays free. The wallet and site checker costs nothing and needs no account, and every other tool starts free. You pay only when you want to track more, watch more or hold more open contracts.
Almstins sits above the payment rails. It does not move money; it helps people check where money is about to go, and keeps a record they can prove later.

Start free. Pay only for more.

Every tool has a free plan. The full table, with what each plan includes, is on the pricing page.
